The marine traffic congestion has increased due to the expansion of vessel traffic volume in Korean coastal waterway these days. Heavy traffic could bring serious marine casualties which cause the loss of human lives, properties and marine pollution in coastal area. In this paper. the probability analysis of marine casualties in Korean coastal To achieve this aim, clears up the cause of accident and examines closely the mutual relations among marine casualties, weather condition, and marine traffic volume. These casualties are classified into several pattens or the point of view of ship‘s size, ship’s type and ship‘s age and its characteristics of each patten are described in detail.

최근 우리나라는 해상 물동량 증가, 조선경기의 호황, 해양레저의 수요증가 등으로 인해 해상에서의 선박 교통량이 점점 증가 하고, 선박도 대형화가 되어가는 추세로서, 해상에서의 사고 개연성과 대형사고의 발생가능성이 높아지고 있다. 또한 허베이스피리트호의 사고에서 알 수 있듯이 연안에서 일어난 해양사고는 막대한 경제적 피해를 가져왔다. 따라서 본 연구에서는 영해를 포함한 EEZ해역에서의 선박통항량과 해양사고를 조사하여, 해상교통환경을 분석했다.

The Maritime Traffic Safety Audit Scheme was institutionalized in 2009 to provide for professional surveys, measurement and the evaluation of navigational hazards that might occur in coastal waters in the course of marine work. Related researches that dealt with the reform of the Maritime Traffic Safety Audit Scheme found that there were no rules or regulations for verifying whether marine work conformed to audit results and reviewing the exactitude of ship handling simulations which were a crucial part of the scheme. According to the necessity of adopting an ex post facto management system in the field of maritime traffic, this study analyzed the similar audit acts such as the Natural Environment Impact Audit Scheme and the Road Traffic Safety Audit Scheme, and proposed specific articles for revising Maritime Safety Act in order to break out from the institutional inertia of the current Maritime Traffic Safety Audit Scheme. It is expected that a newly proposed legal system for verifying the performance of audit results and the exactitude of audits will help improve maritime traffic safety by eradicating potentially hidden hazards related to marine work.

Until a recent date Wan-do Port have been made efforts to advance its marine policy toward the base of marine distribution industry. Therefore the administration of Wan-do port have been carried out many projects on improvements of harbour system very actively. The improvement of ship traffic system would be one of them. This research examined the general view of present situations of marine traffic system in Wan-do waters area and suggested improvements in ship route and anchorage.

Korea coastal area is highly potential dangerous zone of marine accident due to frequent ship's encounters. VTS center can't identify ship's information because of beyond VHF range. It is also difficult of us to efficiently manage vessel traffic beyond VTS control area, so that it can't prevent marine accident. Presently, korean government is conducting maritime traffic safety assessment according to enlargement of harbor & development of new port but do not have the system which provide danger of information depending on maritime traffic environment with real time. So it is necessary to develop evaluation index which can assess sea risk through the evaluation of maritime traffic environment. In this paper, on the basis of vessel navigator's risk consciousness, we carried out survey & statistical analysis vessel navigator's subjective risk depending on the LOA, crossing situation($045^{\circ}$, $090^{\circ}$, $135^{\circ}$), overtaking, head-on situation, encountering vessel's side, within or outside harbor, speed with other vessel(ex. same, fast or slow), speed difference with other vessel and distance with other vessel & propose basic expression to develop maritime traffic safety evaluation model. And by using this model, we can confirm that this proposing expression is suitable for domestic maritime traffic environment.

This study proposes marine traffic volume estimation method considering ship speed, a factor excluded from the existing method. Ten days of GICOMS marine traffic data from Pyeongtaek and Dangjin ports was applied to this study. As a result, converted traffic volume with the proposed estimation method showed an increase of 4.41 (${\pm}0.99$) times or decrease of 0.59 (${\pm}0.04$) at most, compared with the existing estimation method. Average marine traffic congestion for each time applying the proposed estimation method showed an increase of 1.43 (${\pm}0.10$) compared with the existing estimation method. The maximum marine traffic congestion for each time was 1.62 (${\pm}0.34$) times higher compared with the existing estimation method. Marine traffic peak time, defined as the highest point of marine traffic congestion, was evaluated to be different from that of the existing method because of distribution of vessel speed. In conclusion, considering ship speed is necessary when estimating marine traffic volume to produce a practical estimate of marine traffic capacity.

해상 교통 환경은 해운 산업이 발전함에 따라 더욱 복잡해지고 다양화되었다. 이에 따라 해상 교통 관제를 시행하는 선박교통관제사 업무의 중요성이 높아졌으며, 효율적인 교통 관제 시스템 지원을 위한 새롭고 다양한 시도들이 이루어지고 있다. 그러나 현재 선박교통관제에 관한 법률에서는 선박교통관제사의 업무에 대해 해양수산부령으로서 항만운영정보시스템에의 자료 입력을 규정하고 있으며, 이는 교통환경 파악 및 교통 관제에 집중하여야 하는 관제사에게 주의력 상실 등 비효율적인 관제 업무를 초래할 수 있다. 따라서 본 연구는 가장 입출항 선박이 많고 해양사고가 많이 발생하였던 부산항 VTS 센터의 관제사를 대상으로 시선측정실험을 실시하여 실제 관제 업무 시 관제 일지가 차지하는 비율을 확인하고자 하였다.

우리나라 연안 해역은 빈번한 선박조우로 인하여 해양사고 발생 잠재 위험이 높은 해역으로 분류되고 있으나 해상교통의 정량적인 평가의 미흡으로 맞춤형 안전대책이 제대로 수립되고 있지 않는 것이 현실이다. 본 연구에서는 해상교통 안전성 평가모델 중 하나인 IWRAP(IALA Waterway Risk Assessment Program)에 대한 기본적인 소개와 함께, 울산항을 대상으로 한 평가 사례 소개, 기존 유사한 연구와의 비교를 하고자 한다.
